Overview

flexoTHERM 400V with aroCOLLECT air source brine collector module act as an alternative to a ground loop heat pump and can be specified in a wide variety of social housing or new build developments.

aroCOLLECT is a three-phase air collector that uses the ambient air temperature to warm the brine fluid just like a ground loop system. The result is a high-efficiency air-to-water heat exchanger that ensures there is no heat loss between the outside and indoors. It features fully modulating ventilators with minimal sound production, which means the system runs very quietly, operating with a very low noise level of 39.8dB(A) (400V, 5kW).

aroCOLLECT features a twin unit connection using balanced Tichelmann piping, reverse return system and is ideal for outdoor use in agricultural, commercial and residential projects.

flexoTHERM and aroCOLLECT are MCS accredited, so may qualify for the RHI scheme.
